Thinking about getting into more autocross type racing and the cam i have now is def not ideal i would say. My setup now is PRC 225s, FAST 92 and a BTR 231/243 .631/.620 If anyone has suggestions let me know...i was think somewhere in the 224/228ish with low lift...something easy on the drivetrain but really just guessing.

Maybe a BTR or Summit Racing stage 1 cam. Should provide good low end torque which is more important than top end hp

TBSOELS1

Yea thats kind of what i had in mind, something like a BTR Stage 1 or Cam Motion Titan 3. Just looking for anyone that actually races their car other than in a straight line.

Summit stage 2 or WS6store Highlift ASA

I would think gears would help more than a smaller cam in auto cross. As for road courses it comes down to how well you manage your gearbox. On most roadcourses I don't see why you would ever be below 3500 rpm.

TBSOELS1

Im sure gears would help but my cam doesnt come i to power until like 4k rpm. Im sure it would be ok for road race but i think it would be too lazy down low for autox

I <3 my Titan 2.

Summitracing

As others have stated, the SUM-8715 Ghost cam (222/233 115+5 .600/.575) has an intake closing point of 43 degrees. SUM-8720 is our high lift Stage 2 truck cam and specs out at 218/227 112 + 2 .600/.600 and has an intake closing point of 39 degrees for even more low end. The lobes on both are very stable at high rpm and spring lift won't be an issue. This also lets you hold in a gear at high rpm as you're making transitions through certain corner sequences. Let us know if you have any questions.

I would talk with successful winning autox and road racers like Sam Strano and see what sort of cam they suggest.

Matt330LS

I'm building a BMW with a 408 for road racing and had Cam Motion make my cam. The specs they suggested were 226/234, 114+4, .612/.597. I don't plan on running the engine past 6200-6500 rpm, and they said that setup will be great for pulling out of corners and down a straight.

Actually your original idea of 224/228 is quite good. 112 lsa and no ground-in advance.

They would likely suggest the stock cam until you learn how to drive unless they are in the business of selling cams! I autocross and if the valvetrain is aggressive enough to hear with the hood closed and the exhaust is all loud and/or choppy they will put you in a modified class and then you will be humiliated by a stock cammed car with a few serious suspension mods, so Be smart about what you need from the car for this, its all tires and brakes. you are doing transitioning corners at ~35mph and trying to go quickly at part throttle you need low off idle torque and response, I put together a stock 4th gen 2.73 automatic car all stock chassis and stock torque converter and at the time all I could afford was a junkyard 4.8 with a 212/218 115lsa and it was awesome. I was right behind an experienced guy with 2015 1LE and I was on 600 tread wear falken snow tires! He had some good tires! Anyways I recently replaced my anemic little 4.8 with a 11:1cr 6.2 and I re-used the same 212/218-115lsa... Boy it really woke that car up and yet I have no doubts she will tech in the same class as before but of course it's really going to be a nice set of summer tires and some fresh brake pads that helps me drop some time this year the most, good luck it's a lot of fun I really still enjoy drag racing but I also found autocross too and it's just a blast! Hopefully everything gets better soon and we can all go race because I already have cabin fever lol

Biggest thing you'll do for a autox/ rr cam is get rid of that heavy monster clutch for something light that allows the engine to accelerate off the corner. A light clutch will also allow for faster rev match downshifts. This is assuming your suspension is sorted and you can drive......if not then nothing will help except for more practice.

CPFIREBIRD74

If you do some math you’ll find, at least for autox that with a higher rev range afforded by the “big” cams will allow more gear and the net result is more power/torque to the tires

im putting together a 310ci with the 54-454 Comp and plan to spin it as high as I can

I would run a reverse split... 227/224 110+1. That would be a dynamic road racing cam with a lot of torque in the midrange.

TBSOELS1

Well i got with cam motion and they spec'd me a new cam, excited to see how it compares to the old cam. Hopefully alot more low to mid range where the old cam was lacking. Probably ditch my y pipe/slp loudmouth with some hooker blackheart true duals as well.

New cam specs:
225/229 duration @ .050''
111 lobe sep, 109 ICL
.604'/.604''

Did you specify an rpm range for them?
Do you record ECM data during a run?
Curious how this will work out for you.

TBSOELS1

I gave them my old cam specs, told them i wasnt happy with the low end performance and wanted something much stronger in the low and mid range and something that would work well in AutoX/RR. This what they spec’d for me so i went with it. Should drive alot better to with less overlap in the new cam.

stockA4

I'm a novice myself and I suggested op try the stock Cam to start his first track event and he's more likely to come back and try again but He's already made up his mind though. I don't know where he autox at but they won't let you drive your first time where I go you have to ride with a few vets first and they certainly would put you in a modified class with that much overlap but honestly what he wants, that's a way better all around cam spec than what he's got now so he's going to be happier with how it drives regardless of how he can drive it at autox

I think you will be very happy
